Unnamed roads: Imlay, Antelope Summit, Rabbithole, [which road did it use here?] Sulphur, [which road?] Black Rock Springs, Mud Meadow Reservoir, Fly Canyon, High Rock Canyon, Massacre Ranch, old SR 8A, [which road?] Upper Lake, Fandango Pass Road, US 395, [which road?] Pothole Spring, Steele Swamp Road, not sure at all after that
This one has really not survived as a through route; if anything has replaced it, it's the Winnemucca to the Sea Highway.
